Desktop Virtual Reality Offers a Novel Approach to Minimize Pain and Anxiety during Burn Wound Cleaning/Debridement in Infants and Young Children: A Randomized Crossover Pilot Study.

Although most scald burn injuries involve children under six, because of the challenges of using head mounted displays with young children there is very little research exploring the use of VR in children under six. The current clinical pilot study measured the analgesic effectiveness of our new desktop VR system (with no VR helmet) in children under six during burn wound care (a within-subjects design with randomized treatment order). Between December 2021-April 2022, nine children with burn injuries (10 months to 5 years age, mean = 18 months) participated. The mean burn size was 10% Total Body Surface Area, range 2-22%. Using nurse's ratings, VR significantly reduced children's pain during burn wound care by 40% on the observational Faces, Legs, Activity, Crying, and Consolability (FLACC) pain scale. Specifically, non-parametric within-subject sign tests compared nurse's ratings of the young patients' pain during burn wound care using usual pain medications with no VR = 6.67, (SD = 2.45) vs. adjunctive Animal Rescue World VR (VR = 4.00, SD = 2.24, p < 0.01). The observational Procedure-Behavior Checklist (PBCL) nurse's scale measured a 34% reduction in anxiety with VR as compared to pharmacologic treatment alone (p < 0.005). Similarly, when using single graphic rating scales the patients' parents reported a significant 36% decrease in their child's pain during VR (p < 0.05), a 38% (p < 0.005) decrease in their child's anxiety during VR, and a significant increase in patients' joy during VR. It can be concluded that during burn wound care with no distraction (traditional pain medications), children under 6 years old experienced severe pain during a 10 min burn wound cleaning session. During burn wound care combining desktop virtual reality and traditional pain medications, the same pediatric patients experienced only mild pain during burn wound cleaning/debridement. VR significantly reduced the children's pain and anxiety during burn wound care.

Factors influencing blood pressure fluctuation in pediatric patients with sickle cell disease in Saudi Arabia: A retrospective single-center cohort study.

OBJECTIVES: To investigate changes in blood pressure (BP) among pediatric patients with sickle cell disease (SCD) and determine the variables that might influence these changes. METHODS: A total of 100 pediatric patients with SCD who followed up in the pediatric outpatient clinic were recruited for this retrospective cohort study. Clinical data included anthropometric measures, average systolic and diastolic BP recorded during multiple follow-up visits, hemoglobin (Hb) level, serum creatinine, and hemoglobin S percentage. Blood pressure measurements were categorized according to the guidelines of the American Academy of Pediatrics (AAP, 2017). RESULTS: In this cohort, 68% of the patients had normal systolic BP, 13% had elevated systolic BP, 17% had stage 1 hypertension (HTN), while only 2% reported stage 2 HTN. Patients who were overweight had relatively high systolic BP compared to patients who were underweight (p=0.034) or had normal weight (p=0.023). The average systolic BP significantly correlates with body mass index (r= 0.377, p<0.001) and serum creatinine (r=0.369, p<0.001). CONCLUSION: Pediatric overweight SCD patients exhibited higher average systolic BP than those underweight or normal weight. Body mass index and serum creatinine significantly influenced the average systolic BP more than the Hb level or Hb S percentage.

Parental Knowledge and Awareness about Shaken Baby Syndrome in Jeddah, Saudi Arabia: A Cross-Sectional Study.

BACKGROUND: Despite the serious consequences of shaken baby syndrome (SBS), previous studies revealed a low level of knowledge among Saudi parents. METHODS: This is a cross-sectional study. An electronic questionnaire was distributed through social media platforms to parents of pediatric age group children in Jeddah, Saudi Arabia. A total of 524 responses were received. Data about participants' demographics, knowledge, attitude, and practice regarding SBS were collected through convenient random sampling. RESULTS: A total of 524 responses were received; 30.7% of the participants were familiar with SBS. The Internet and the social media platforms were the most common sources of information. There was no statistically significant correlation between knowledge levels and participants' sociodemographic factors; only 32.3% of individuals had good knowledge. Of them, 84% had a positive attitude towards learning more about SBS, and 40.1% and 34.3% were interested in learning more about SBS before and during pregnancy, respectively. Carrying the baby and shaking were the actions most frequently taken when a baby was crying. Of them, 23.9% forcefully shake their child, while 41.4% of them throw their infant up in the air and catch it. CONCLUSIONS: It is important to conduct health education programs on SBS for mothers throughout the prenatal period.

Virtual Reality Animal Rescue World: Pediatric virtual reality analgesia during just noticeable pressure pain in children aged 2-10 years old (crossover design).

Background and aims: Excessive pain during medical procedures is a worldwide medical problem. Most scald burns occur in children under 6, who are often undermedicated. Adjunctive Virtual Reality (VR) distraction has been shown to reduce pain in children aged 6-17, but little is known about VR analgesia in young children. This study tests whether desktop VR (VR Animal Rescue World) can reduce the just noticeable pressure pain of children aged 2-10. Methods: A within-subject repeated measures design was used. With treatment order randomized, each healthy volunteer pediatric participant underwent brief cutaneous pressure stimuli under three conditions: (1) no distraction, (2) a verbal color naming task (no VR), and (3) a large TV-based desktop VR distraction. A hand-held Wagner pressure pain stimulation device was used to generate just noticeable pain sensations. Participants indicated when a steadily increasing non-painful pressure stimulus first turned into a painful pressure sensation (just noticeable pain). Results: A total of 40 healthy children participated (43% aged 2-5 years; and 57% aged 6-10 years). Compared to the no distraction condition, the 40 children showed significant VR analgesia (i.e., a significant reduction in pain sensitivity during the VR Animal Rescue World condition), t(39) = 9.83, p < 0.001, SD = 6.24. VR was also significantly more effective at reducing pain sensitivity vs. an auditory color naming task, t(39) = 5.42, p < 0.001, SD = 5.94. The subset of children aged 2-5 showed significant reductions in pain during VR. Children under 6 showed greater sensitivity to pain during no distraction than children aged 6-10. Conclusion: During no distraction, children under 6 years old were significantly more sensitive to pain than children aged 6-10. Virtual reality (VR) significantly reduced the "just noticeable" pressure pain sensitivity of children in both age groups.

An MRI Scans-Based Alzheimer's Disease Detection via Convolutional Neural Network and Transfer Learning.

Alzheimer's disease (AD) is the most common type (>60%) of dementia and can wreak havoc on the psychological and physiological development of sufferers and their carers, as well as the economic and social development. Attributed to the shortage of medical staff, automatic diagnosis of AD has become more important to relieve the workload of medical staff and increase the accuracy of medical diagnoses. Using the common MRI scans as inputs, an AD detection model has been designed using convolutional neural network (CNN). To enhance the fine-tuning of hyperparameters and, thus, the detection accuracy, transfer learning (TL) is introduced, which brings the domain knowledge from heterogeneous datasets. Generative adversarial network (GAN) is applied to generate additional training data in the minority classes of the benchmark datasets. Performance evaluation and analysis using three benchmark (OASIS-series) datasets revealed the effectiveness of the proposed method, which increases the accuracy of the detection model by 2.85−3.88%, 2.43−2.66%, and 1.8−40.1% in the ablation study of GAN and TL, as well as the comparison with existing works, respectively.

Association Between Early Childhood Caries and Obesity among Preschool Children.

PURPOSE: Early childhood caries (ECC) and childhood obesity are among the most prevalent health conditions affecting children. ECC is associated with obesity through the common risk factor of sugar consumption. The present study aimed to assess the association between ECC and obesity in preschool children. MATERIALS AND METHODS: A cross-sectional study was conducted among 1250 preschool children (698 girls, 552 boys; mean age: 4.3 [1.1] years). The children's body mass index was determined (BMI: weight/height in kg/m2). The World Health Organization criteria were used for the diagnosis of caries. Multivariable logistic regression was used to analyse the relationship between ECC prevalence and childhood obesity. RESULTS: ECC was detected in 929 (74.3%) children. The mean dmft and dmfs was 5.91 (1.13) and 8.92 (2.07), respectively. The multiple regression model showed a statistically significant association between ECC prevalence and obesity with an adjusted odds ratio (OR) of 2.59 (95% CI: 1.88 - 3.57; P = 0.001). The logistic regression model showed that in children with a monthly family income > $2666, sugar consumption, preterm low birth-weight/full-term low birth-weight (PTLBW/FTLBW), and toothbrushing frequency ≤ 1 time/day were statistically significantly associated with ECC prevalence. CONCLUSION: ECC was positively associated with obesity.

Dental Erosion Prevalence and Its Association With Obesity Among Children With and Without Special Healthcare Needs.

PURPOSE: Dental erosion and childhood obesity are associated with a common risk factor, soft drink consumption. The present study aims to assess the prevalence of dental erosion and its association with obesity among children with and without special healthcare needs. MATERIALS AND METHODS: A cross-sectional study was conducted on 1,200 school children (400 children with special needs (CSHN) and 800 children without special needs) in the age group of 6 to 16 years. Dental erosion was diagnosed according to World Health Organization (WHO) criteria. Body mass index (BMI; weight/height in kg/m2) was recorded for each child. The association of dental erosion and obesity was analysed using multivariate logistic regression analysis. RESULTS: A total of 331 (27.6%) children presented with dental erosion. Dental erosion prevalence among CSHN was 33.5% and among children without special needs was 24.6%. In the final fully adjusted model, children with obesity presented 2.32 times (95%CI 1.17-4.89, P = 0.001) higher odds ratio (OR) of having dental erosion than normal-weight children. Children who consumed soft drinks ≥ 1 time/day and 2-6 times a week presented with an OR of 2.65 (95%CI 1.23-5.21, P = 0.001) times of dental erosion. Children with chronic vomiting and bulimia presented with a 3.27 (95%CI 1.72-6.12, P = 0.001) times higher OR of dental erosion. Children with gastric reflux presented with a 3.21 (95%CI 1.52 - 5.86, P = 0.001) times higher OR of dental erosion. CONCLUSION: The prevalence of dental erosion was slightly higher for special needs children compared to children without special needs. The study outcome suggests that obesity, chronic vomiting, consumption of soft drinks, and gastric reflux are statistically significantly associated with dental erosion.

Incidence and predictors of bacterial infections in febrile children with sickle cell disease.

INTRODUCTION: Sickle cell disease (SCD) is an autosomal recessive disorder. The incidence of bacterial infection in children with SCD globally is 16% compared 3-14% in general children. Bacterial infection in children is a severe problem and is considered to be a life-threatening condition. To reduce antibiotic overuse, the following factors might be associated with bacterial infection could help: age, C-reactive protein (CRP), white blood cells (WBCs) count, absolute neutrophil count (ANC), and genotype. Therefore, this study is designed to evaluate the CRP, ANC, WBCs, and platelet count levels as predictors for bacterial infection in febrile children with sickle cell anemia over a six-year period in a tertiary center in Jeddah, Saudi Arabia. METHODS: This study was a retrospective record review that included all SCD patients below the age of 18 years who presented with a febrile episode at any hospital's department from 2017 to 2019. Data were extracted from patient files that included culture result and the causative organism, CRP level, WBCs, ANC, and platelet count. RESULTS: The study included 62 children diagnosed with SCD who presented with 89 febrile episodes. There was no statistically significant difference in the median of CRP and ANC between the bacterial and nonbacterial febrile episodes (P = .314, .735, respectively). However, the level of WBC> 20 K/µL was statistically significant at P = .025. CONCLUSION: WBCs significantly associated with a bacterial infection in SCD febrile children along with clinical assessments. This parameter can guide the physicians to determine the children at high risk of bacterial infection.

A Cross-Sectional Study of Detection of Beta Globin (HBB) Haplotypes Among Beta Thalassemia Patients.

Introduction Beta-thalassemia is among the most common monogenic disorders in the Arabian Peninsula. This study aimed to investigate the ß-globin (HBB) haplotypes among ß-thalassemia patients in Saudi cohort which have potential implications in understanding the clinical care of patients and population genetic factors associated with ß-thalassemia. Methods We analyzed 60 ß-thalassemia patients. Male/female distribution for ß-thalassemia was 58.33%/41.66%. Results of hematological parameters and indices were obtained from the database. HBB haplotyping assay was performed for four specific loci of the HBB gene cluster using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. Results HBB haplotyping assay identified three novel patterns namely haplotype 1, haplotype 2, and haplotype 3 and three common African haplotypes including Benin, Senegal, and Cameron. The frequency of haplotype 1 was the highest among the studied samples (62%, n = 37) with 56.76% (n = 21) observed in males compared to 43.24% (n = 16) in females. This was followed by Senegal, haplotype 2, Benin and haplotype 3 with similar percentage, and Cameron haplotype with 18%, 12%, 3% and 2%, respectively. The relationship between these haplotypes and various hematological parameters was calculated and our study found no significant relationship (p-value >0.05). Conclusion Our study indicated the importance of finding out types of ß-globin haplotypes as novel types being discovered. Though no statistically significant association was identified among all the haplotypes in terms of hematological parameters, Cameroon or Benin haplotypes had the mildest form because they have the highest means among all parameters. Further studies need to be carried out on a larger population to detect the frequency of each specific mutation in each haplotype among ß-thalassemia patients. This would help to re-address the question of the origin(s) of the ß-thalassemia.

Hydroxyurea Use Among Children With Sickle Cell Disease at King Abdulaziz University Hospital in Jeddah City.

Background Sickle cell disease (SCD) is an autosomal recessive hemoglobinopathy that is very common and causes a great burden in Saudi Arabia and worldwide. This study aims to determine the frequency and benefits of using hydroxyurea in treating children with SCD in King Abdulaziz University Hospital (KAUH) in Saudi Arabia. Method This retrospective observational study included all SCD patients, males and females, who were following up in KAUH and were less than 18 years old. Patients on chronic transfusion therapy or who had previous stem cell transplantation were excluded from the study. The study was approved by the unit of biomedical ethics in KAUH, Jeddah. Result The study included 102 SCD patients; the median age of the sample was 7.5±4.2, with the majority being female (58 patients; 56.9%). Hydroxyurea users among participants in the study were 62 patients (60.8%). Thirty-seven (37) of the patients using hydroxyurea had an increase in the mean corpuscular volume (MCV). There was a decrease in the level of white blood cells (WBCs) and neutrophil count from 15.81±10.24 and 48.31±23.23% to 12.48±5.48 and 40.81±15.78%, respectively. Platelet count showed an increase from 345.4±2.1096 to 359.162±199.87 after starting hydroxyurea. The incidence of vaso-occlusive crisis (VOC) increased after hydroxyurea initiation from 4.555±4.08 to 6.288±9.80. Moreover, the frequency of blood transfusion in patients using hydroxyurea was statistically significant as p-value = 0.048. Conclusion In conclusion, our results showed significant clinical and laboratory benefits of hydroxyurea in children with SCD. Hydroxyurea has been shown to reduce the frequency of VOC and blood transfusion in patients with SCD.

Risk Factors and Complications Among Pediatric Patients With Sickle Cell Anemia: A Single Tertiary Center Retrospective Study.

Background and objective Sickle cell anemia (SCA) is one of the common genetic diseases in the Kingdom of Saudi Arabia (KSA). This disease results from a genetic mutation that causes malformation of the red blood cells (RBCs), leading to various systemic complications, including vaso-occlusive crisis (VOC), acute chest syndrome (ACS), osteomyelitis, avascular necrosis (AVN), and stroke, to name a few. The leading cause of mortality in SCA is these systemic complications rather than the disease itself. Understanding the risk factors of these complications can help reduce mortality in these patients and improve their quality of life. In this study, we aimed to determine the risk factors of SCA complications among pediatric patients with SCA at King Abdulaziz University Hospital (KAUH) in Jeddah, KSA. Methods This retrospective study was carried out from January 2012 till June end 2019. It was conducted among pediatric patients with SCA. Patients were screened for eligibility, and we excluded those with thalassemia and those who had a medical history of chronic diseases. Data were collected from patients' electronic medical records. Results The study included 102 pediatric patients with SCA; their mean age was 7.88 ±4.22 years; almost half of them were females (56%) and 44% were males. The dominant body mass index (BMI) classification among them was normal (49%). Urinary tract infection (UTI) was the most common complication with 38 cases followed by VOC with 32 cases. Other complications observed were ACS (25.5%) followed by stroke (15.7%). HbSS was the most prominent genotype among these patients, and it was associated with a higher rate of complications. However, there was no significant relationship between genotype and patients developing complications. Finally, patients with high white blood cell (WBC) counts, elevated systolic blood pressure (SBP), and hypoxia developed more complications, and there was a significant relationship between these conditions and the development of complications (p<0.05). Conclusion Based on our findings, patients with high WBC count, elevated SBP, and hypoxia are at greater risk of developing complications. Accordingly, healthcare providers should consider putting in place all measures required to provide a good quality of life for these patients, including raising awareness about the risk factors that lead to these complications, appropriate immunizations, and precautionary measures to promote these patients' welfare.

Association Between Dental Caries and Obesity among Children with Special Health Care Needs.

PURPOSE: Obesity and dental caries constitute an important public health problem worldwide. Special-needs children are at higher risk of developing dental caries and obesity because of their physical, neurological, or behavioural impairment or due to side effects of the medications they take. The present study was conducted to assess the association between dental caries and obesity among children with special health care needs in Taif City, Saudi Arabia. MATERIALS AND METHODS: A descriptive cross-sectional study was conducted among 400 (220 girls and 180 boys) special-needs children. Body mass index (BMI) was determined by using height and weight measurements. Dental caries was recorded according to World Health Organization criteria. The association between caries and obesity was assessed using multivariable logistic regression analysis. RESULTS: 289 (72.3%) children presented with caries with mean dmft and DMFT of 3.9 ± 2.7 and 4.8 ± 2.3, respectively. Regression analysis showed specials needs children were at a greater risk of having dental caries: 1.69 times (CI: 0.18-2.62, p < 0.05) greater with obesity; 2.01 (CI: 0.18-3.09, p < 0.05) times greater with sugar consumption; 2.21 times (CI: 1.27-4.12, p < 0.001) greater with cerebral palsy; and 2.27 (CI: 1.29-5.12, p < 0.001) times greater with intellectual disability. CONCLUSION: The present study showed a positive association between dental caries and obesity among children of special health care needs. Hence, a focused approach towards the common risk factors is essential to prevent both obesity and dental caries in special-needs children.

Self-assembling peptide P11-4 in remineralization of enamel caries - a systematic review of in-vitro studies.

OBJECTIVE: The present systematic review was conducted to investigate the effect of the self-assembling peptide (SAP) - P11-4 in the remineralization of enamel caries. MATERIAL AND METHODS: The systematic search for studies was conducted through CINAHL, EMBASE, MEDLINE, Scopus, PsychINFO, and various key journals. This review was conducted in adherence to PRISMA standards and was registered in PROSPERO with registration number CRD42019110156. The methodological quality of the studies was graded through Cochrane's tool of risk of bias in non-randomized studies - of interventions (ROBINS-I). RESULTS: In total, 91 studies were identified for screening, and 12 studies were eligible. Ten studies showed effective enamel remineralization with P11-4 compared to controls. One study showed a combination of P11-4 with fluoride varnish or Casein Phosphopeptide-Amorphous Calcium Phosphate Fluoride (CPP-ACPF) leads to significantly higher remineralization compared to P11-4 alone. Quality assessment of study showed 6 (50%) studies as medium risk of bias and 6 (50%) studies as low risk of bias. CONCLUSION: To conclude, the present study results showed SAP- P11-4 is effective in the remineralization of enamel caries.

Hemoglobin Disorders Among Anemic Patients: a Cross-Sectional Study from Jeddah City, Western Saudi Arabia.

BACKGROUND: Hemoglobinopathies and thalassemia are defined as a group of inherited blood disorders characterized by a variable degree of anemia with a wide spectrum of clinical symptoms. They are commonly found in the Mediterranean area, sub-Sahara Africa, Middle East, Central India, and Southeast Asia with an estimation of 400,000 babies born annually with serious hemoglobinopathies. Of those, 90% of the births occur in underdevel-oped or developing countries. This study was undertaken to investigate the prevalence of hemoglobin disorders among anemic patients who visited a tertiary care setting represented by King Abdulaziz University Hospital. METHODS: This is a cross sectional study which investigated blood samples from 668 anemic patients for possible causes of anemia. This investigation involved the use of complete blood count, hemoglobin separation using capillary electrophoresis, and measurement of nutritional elements commonly investigated for anemia. RESULTS: We found that the frequency of different types of hemoglobinopathies and thalassemia among the subjects were as follow; normal (HbAA) 439 (65.7%); Sickle Cell Trait (HbAS) 65 (9.7%); Sickle Cell Anemia (HbSS) 63 (9.4%); ß-thalassemia trait 48 (7.2%); Hb S/ß 27 (4.0%); HbH 7 (1.0%); HbE 6 (0.9%); beta-thalassemia major 6 (0.9%); Hb E/beta-thalassemia 4 (0.6%); HbC 1 (0.1%); HbD 1 (0.1%) and HbSC 1 (0.1%). CONCLUSIONS: The findings of this study emphasize the necessity of increasing public health education, neonatal and adult screening programs, as well as nutritional guidance and plans to start the eradication of this burden.

Detection of BCL11A and HBS1L-MYB Genotypes in Sickle Cell Anemia.

Sickle Cell Anemia (SCA) is one of the most common monogenic disorders worldwide. Molecular modifiers of clinical symptoms play an essential role in the amelioration of the effects of the disease. Single Nucleotide Polymorphisms (SNPs) of the BCL11A gene and within the HBS1L-MYB intergenic region, which are located outside the ß-globin locus on chromosome 11, are considered to be genetic modifiers that are associated with elevated levels of foetal haemoglobin HbF, and thus they reduce the clinical impact of sickle haemoglobin, HbS. The work reported here aimed to detect the most common SNPs of BCL11A and HBS1L-MYB related to HbF in SCA patients and to estimate the frequency of occurrence of these genotypes. A total of 132 SCA patients whose condition was stable were recruited from Jeddah city, Saudi Arabia. SNPs at site locus rs4671393 on BCL11A, and at loci rs28384513 and rs9399137 on HBS1L-MYB were identified using TaqMan genotyping assay. Haematological parameters were analysed based on complete blood count and haemoglobin separation using the capillary electrophoresis technique. Highly significant differences in the diagnostic haematological parameters, including all blood-cell types and HbF, were observed between the study cohort and control groups. We also found that BCL11A rs4671393 genotypes of GG and AG were more likely to show increases in HbF levels than other genotypes. In addition, a strong relationship was found between HBS1L-MYB rs9399137 and rs28384513 genotypes in the cohort, whereas no significant association was observed between BCL11A rs4671393 variant and other variants. Our study highlights the importance of investigating genetic determinants that play roles in the amelioration of the severity of clinical symptoms and complications of SCA.

Prevalence and Risk Factors for Microalbuminuria in Children with Sickle Cell Disease at King Abdulaziz University Hospital: A Retrospective Cross-sectional Study.

OBJECTIVES: Previous studies have not addressed microalbuminuria in pediatric patients with sickle cell disease (SCD) in Jeddah, Saudi Arabia. This study aimed to determine the prevalence of microalbuminuria and to identify associated risk factors in children with SCD at King Abdulaziz University Hospital. RESULTS: Overall, 42.5% of the patients enrolled were Saudi Arabian and 51% were male. The mean age was 12.4 years, and the highest percentage (40%) was in the age group of 15-18 years. The prevalence of microalbuminuria was 9.6%, and hematuria was present in 8% of cases. The percentage of patients with hematuria was significantly higher in the microalbuminuria group (22.6%) than in the nonmicroalbuminuria group (6.5%; P = 0.007). The percentage of patients with acute chest syndrome was also higher in the microalbuminuria group (26%) than in the nonmicroalbuminuria group (8%; P = 0.005). The percentage of patients with gallbladder stones was higher in the microalbuminuria group (13%) than in the nonmicroalbuminuria group (2.4%; P = 0.014). However, the mean number of blood transfusions was higher in the nonmicroalbuminuria group than in the microalbuminuria group (P = 0.002). Sickle cell nephropathy manifests as microalbuminuria, begins at an early age, occurs in all types of SCD, and is associated with disease severity.

Association between soft drink consumption, gastric reflux, dental erosion, and obesity among special care children.

OBJECTIVES: This study assessed the association between soft drink consumption, gastric reflux, dental erosion, and obesity among special care children. MATERIALS AND METHODS: A total of 350 special care children (male-131, female-219) mean age of 12.6 (± 2.6) years were included. Detection of dental erosion was performed according to the World Health Organization criteria. The medical evaluation assessed body mass index (BMI). With appropriate sample weighting, relationships between dental erosion prevalence and obesity were assessed using multivariable logistic regression. RESULTS: Overall prevalence of dental erosion was 36%. Mean BMI for entire study population was 24.7 (± 7.8). Regression analysis showed strong association between dental erosion prevalence and consumption of soft drinks (adjusted odds ratio = 1.8; 95% CI = 0.71-2.92, P < .05), bulimia (adjusted odds ratio = 2.27; 95% CI = 0.99-4.28, P < .001), and gastric reflux (adjusted odds ratio = 2.24; 95% CI = 0.82-4.1, P < .001). Bivariate analysis showed high prevalence of dental erosion among obese children compared to children with normal weight (P = .04). CONCLUSION: The present study demonstrated a significant association between dental erosion prevalence and consumption of soft drinks and gastric reflux among special care children.

Anaesthetic efficacy of articaine versus lidocaine in children's dentistry: a systematic review and meta-analysis.

BACKGROUND: Over the last few years, numerous reviews and studies have awarded articaine hydrochloride local anaesthetic (LA) a superior reputation, with outcomes of different studies demonstrating a general tendency for articaine hydrochloride to outperform lidocaine hydrochloride for dental treatment. Nevertheless, there seems to be no clear agreement on which LA solution is more efficacious in dental treatment for children. There is no previous publication systematically reviewing and summarising the current best evidence with respect to the success rates of LA solutions in children. AIMS: To evaluate the available evidence on the efficacy of lidocaine and articaine, used in paediatric dentistry. DESIGN: A systematic search was conducted on Cochrane CENTRAL Register of Controlled Trials, MEDLINE (OVID; 1950 to June 2017), Cumulative Index to Nursing and Allied Health Literature (CINAHL; EBSCOhost; 1982 to June 2017), EMBASE (OVID; 1980 to June 2017), SCI-EXPANDED (ISI Web of Knowledge; 1900 to June 2017), key journals, and previous review bibliographies through June 2017. Original research studies that compared articaine with lidocaine for dental treatment in children were included. Methodological quality assessment and assessment of risk of bias were carried out for each of the included studies. RESULTS: Electronic searching identified 525 publications. Following the primary and secondary assessment process, six randomised controlled trials (RCT) were included in the final analysis. There was no difference between patient self-reported pain between articaine and lidocaine during treatment procedures (SMD = 0.06, P-value = 0.614), and no difference in the occurrence of adverse events between articaine and lidocaine injections following treatment in paediatric patients (RR = 1.10, P-value = 0.863). Yet, patients reported significantly less pain post-procedure following articaine injections (SMD = 0.37, P-value = 0.013). Substantial heterogeneity was noted in the reporting of outcomes among studies, with the overall quality of majority of studies being at high risk of bias. CONCLUSIONS: There is low quality evidence suggesting that both articaine as infiltration and lidocaine IAD nerve blocks presented the same efficacy when used for routine dental treatments, with no difference between patient self-reported pain between articaine and lidocaine during treatment procedures. Yet, significantly less pain post-procedure was reported following articaine injections. There was no difference in the occurrence of adverse events between articaine and lidocaine injections following treatment in paediatric patients.

Anaesthetic efficacy of 4% articaine and 2% lidocaine for extraction and pulpotomy of mandibular primary molars: an equivalence parallel prospective randomized controlled trial.

AIM: To compare the anaesthetic efficacy for pain and behaviour during treatment with mandibular infiltration using 4% articaine (BI) with inferior dental nerve clock (IDNB) using 2% lidocaine for extraction or pulp therapy in mandibular primary molars. DESIGN: This was equivalence parallel prospective RCT. A total of 98 children aged 5-9 years old were randomly assigned into two groups: BI supplemented by buccal intrapapillary infiltration with 4% articaine; IDNB with 2% lidocaine supplemented with long buccal infiltration. Behaviour during the injection and treatment procedures was assessed using Wong-Baker Facial Rating Scale (W-BFRS), Visual Analogue Scale (VAS), and Frankl Behaviour Rating Scale (FBRS). RESULTS: During the injection phase, the absolute differences in success rates between the two techniques were 0.06 (95% CI: -0.11 to 0.23) for VAS and -0.08 (95% CI: -0.19 to 0.03) for the behaviour of the child (FBRS). FBRS results showed the equivalence of the two, whereas the VAS results showed nonequivalence with the 95% confidence intervals slightly exceeding the equivalence margin (±0.20). W-BFRS success rates were 63.3% for both. During the treatment, VAS results showed similar success rates, demonstrating equivalence between the two as did the results for FBRS. CONCLUSION: The results suggested equivalence in success rates for both anaesthetic techniques during treatment.

ARL6IP6, a susceptibility locus for ischemic stroke, is mutated in a patient with syndromic Cutis Marmorata Telangiectatica Congenita.

Cutis Marmorata Telangiectatica Congenita (CMTC) is a congenital localized or generalized vascular anomaly, usually sporadic in occurrence. It can be associated with other cutaneous or systemic manifestations. About 300 cases have been reported. The molecular etiology remains largely unknown. The main purpose of this study is to delineate the molecular basis for a syndromic CMTC phenotype in a consanguineous Saudi family. Clinical phenotyping including detailed neurological imaging, followed by autozygosity mapping and trio whole exome sequencing (WES) are also studied. We have identified a homozygous truncating mutation in ARL6IP6 as the likely cause of a syndromic form of CMTC associated with major dysmorphism, developmental delay, transient ischemic attacks and cerebral vascular malformations. This gene was previously implicated by genome wide association study (GWAS) as a susceptibility locus to ischemic stroke in young adults. We identify ARL6IP6 as a novel candidate gene for a syndromic form of CMTC. This suggests that ischemic stroke or transient ischemic attacks (TIA) may represent, at least in some cases, the mild end of a phenotypic spectrum that has at its severe end autosomal recessive CMTC. This finding contributes to a growing appreciation of the continuum of Mendelian and common complex diseases.
